说明：  MATLAB中plot函数的典型应用，适合初学者熟悉绘图函数(MATLAB plot function in a typical application, suitable for beginners familiar with the drawing functions)

从初值出发，先计算y对时间t的导数，得到y的变化速度；求出x对t的导数，得到x随时间的变化速度。然后时间前进一小步h=0.002，同时x和y也都发生一个小的变化，即在原来数值基础上加上时间步长h和变化速度的乘积。如果x到达1或者-1，强制让y发生变化。这个过程不断迭代，得到结果。 (completed chart)
